What I learned about html

I have learned that html is the simple coding part when it comes to making your web page. CSS is basically what makes it pretty and colorful. In my com class we have also worked with html and it is very simplistic, compared to CSS. Html is very plain Jane, and basic, while CSS is used to help apply color and change more specific things.  Html is used mostly to do things like size and position of things. For example the size of charts and bars and things that you want have on your site. I thought initially they were the same thing, but now I know that is not true.
